HEAT TRANSFER, INSULATION, AND FREEZE PROTECTION

HEAT TRANSFER, INSULATION, AND FREEZE PROTECTION 5.61

Special Installation Considerations
Large pumps, instruments, and other irregularly shaped pieces of equipment must also be
protected. These pieces of equipment generally require that the tracer be either directly
in contact with the object being protected or, in cases where overheating cannot be toler-
ated, isolated from that equipment by spacers between the tracer and equipment or by tape
wound around the tracer to reduce the surface temperature of the tracing pipe. Special
design details for tracing methods must be custom made for specific pieces of equipment.
Because it is common to find dirt and debris in the tracer line, it is important that it be
blown out with steam before being placed in service.
